Learning

                                            Learning Meaning of learning- Modification of behaviour through training and experience is called Learning. Leraning may be felt into two aspects- On the one hand a man constitute by himself learning or gaining something. On the other hand the environment  requires to be learnt something for some purposes. So we can say....... " Learning is the key process in human behaviour. " Nature of Learning- Learning is connected to life and Life is connected to learning. Infact Life is nothing without learning. Life can not take even a step without learning. Life is dead without learning. There is a reversible sign b/w life and learning.                                                                                     Life⇌Learning                        Life and learning both are complementary to each other.  3.In the whole process of learning needs          arise but goal is set up.  4.adjustments are made in the lif

Cell organelles

                                      Cell Organelles The components of the cells which helps in construction and functioning of the crkl are called organelles. Infact organelles are the parts of the cell itself. Different organekles perform different functions of the cell such as Ribosome synthesize protein, Mitochondrion provide energy to cell cell, Nucleus keep chromoso- mes safe and separate from other substance and Golgi body or Golgi apparatus  secrtes the hormones etc. The major group of the cell organelles 1- Plasma membrane 2- Cytoplasm 3- Nucleus  Name of the cell organelles Living parts of a cell 1- Plasma membrane 2- Cytplasm i- Endoplasmic Reticulum (ER) a- Smooth ER b- Rough ER ii- Mitochibdrion iii- Golgi Apparatus iv- Ribosomes v- Lysosomes vi- Centrioles vii- Plastids 3- Nucleus Non-living parts of the cell i-  Cell Wall ( in plants only) ii- Vacuoles iii- Granules ( Cell inclusions) Plasmamembrane Nature of Plasmamembrane 1- Each and e

matter

            Matter in our surroundings Matter is anything that has mass and occupies space. S.I. unit of mass and volume is kilograme and cubic metre ( m3). respectively. Matter can be classified into two groups based on the physical and chemical properties. On the basis of physucal properties matter can be divided into gas, liquid and solid. On the bases of chemical properties matter can be divided into Elements , Compound and mixture. Solid has fixed shape  and volume . Liquid do not have fixed shape . Gas has neither fixed volume  nor shape . Every matter is composed of certain particles which are differ in shape  , size  and Volume. 10.Particles of matter have a tendency to diffuse. 11-States of matter can be interchanged by changing its temperature or pressure.           Some important definitions  1- Diffusion- When the particles of the matter of higher concentration move to the the matter of lower concentration. This event is called Diffusion. 2- Fusion- Wh
